81岁拜登体检结果出炉！

US President Biden on Wednesday was declared "fit for duty" by his longtime doctor, who said that the president had undergone an "extremely detailed" neurological exam that did not turn up evidence of stroke, neurological disorders or Parkinson's disease.

White House physician Kevin O'Connor said that a team of doctors, including a neurologist, two orthopedists and a physical therapist, examined the president, whom Dr. O'Connor described as an “active 81-year-old white male.”

On Wednesday, Biden answered questions about the results of his exam with a joke. "They think I look too young," he told reporters during a round table with law enforcement officials at the White House. "There is nothing different than last year," he said, adding that "everything's great."

In a summary of Biden's third presidential physical at Walter Reed National Military Medical Center, Dr. O'Connor did not say whether the examination contained common tests for assessing cognitive decline or detecting signs of dementia that are often recommended for older adults.

Earlier in the day, Karine Jean-Pierre, the White House press secretary, declined to give specifics about the tests Biden had undergone, but said that the president "doesn't need" a cognitive exam. 

Biden has obstructive sleep apnea, a common sleeping disorder in which a person’s airways become blocked. Dr. O’Connor noted that the patient had been “remarkably committed to sticking with therapy” and sleeps nearly every night with a machine that helps his airways clear.
